Nirvana did a version of 'In The Pines' in their Unplugged set: the song has a long folk / country history. This link - www.nirvanafreak.net/art/art49.shtml - tells a lot about the song.
Mickey took that history and - as with American Trilogy, Danny Boy, Shenandoah and His Eye Is On The Sparrow - made the song's history his own.
